IMPROVEMENT IN STEAM ROAD-WAGONS.

Specification forming part of Letters Patent No. 222,352, dated December9, 1879 application filed 5 October 10, 1879.

1 To all whom it may concern:

I Newport, in the county of Herkimer and State of New York, haveinvented certain new and useful Improvements in Steam Road-Wagons; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon,which form a part of this specification, in which Figure 1 is a sideview of the road-Wagon Fig. 2, a plan view; Fig. 3, a bottom view I witha portion cut away.

In the accompanying drawings, the letter A indicates the cylindricalcasing of a returnflue boiler, the fire-box B being under the smoke-flueO, and in front of the fire-box there is a platform, D, for theengineer. The waterbox E is under the boiler, and the coal-box F is infront of both the boiler and the waterbox. I

The steering apparatus is at the forward end of the wagon, and consistsof a worm, G, journaled in brackets H, and provided with cranks I, andmeshes with a wheel, J, the teeth of which are cut 'so as to conform tothe pitch of the Worm. I

The worm-wheel is on top of a shaft, K, which has. a pinion, L, at itslower end, that gears with the teeth on the inside curve of a segmentalbar, M, that is bolted to the arms N, extending forward from the frontaxle, O, of the wagon, said axle being pivoted to the bar P, whichextends from front to rear of forward part of the wagon, as shown inFig. 1.

The letter A indicates the drive-wheels of the wagon, interiorly cogged,as shown, and a pinion, B, gears therewith. The pinion B is on a shaft,0, journaled in blocks D, which are bolted or otherwise secured to theunder side of the longitudinal bars E F. To the other end of said shaftthere is keyed or otherwise secured a gear-wheel, G, which engages witha spur-wheel, H, on the end of a shaft, I, which is journaled in blocksJ, bolted to the bars E F, and on the said shaft, between the two bars EF, there is a band-wheel, K, to which motion is imparted by means of aband, belt, or chain connecting with another wheel rotated through theinstrumentalitiesof levers and gearing, the construction, arrangement,and operation of which it is here unnecessary to describe, inasmuch asthey are all well known to persons skilled in the art of constructingengines. Y

The shaft 0 is so located with reference to the drive-wheel A that thepinion B will gear with the cogs thereof at a point in front of and onthe same plane with the axle of the drive-wheel, and this location ofthe said pinion with relation to the said drive-wheel and its axle isone point of my invention, for by so locating it I get the power appliedon a horizontal plane with the center of the drive 'wheel and relievethe axle of considerable pressure 5 and practical application hasdemonstrated that the power is applied. with more effect at that pointthan at any other.

The brake for this wagon consists of two levers, L L connected to eachother by means of two vertical rods, M. The lower lever, L,

has two arms, N N the arm N being the rod extending from side to side ofthe wagon.

One of the vertical rods M is hooked or 7 otherwise secured to the shortarm of the lever L, the other end thereof being similarly connected tothe arm of the lever L above it, while the other vertical rod isconnected to the end of the other arm of the upper lever and to the longarm of the lower lever some Way back from its end. I

A coiled or other spring, Q, placed'around one or both of the verticalrods M, and bearing against the arm of the upper lever and a plate, Qbelow it, forces the top lever up from off the band-wheel when the brakeis to be released.

The top lever, L, consists of two arms, R,

and connecting-rod R the arms being curved, as shown, and provided withshoes S, tobear on the band-wheels K when thebrake' is applied, and therod R extends from side to side of the wagon, resting on the frame wheelK and spur-wheel H, gear-wheel G and pinion B, and drive-wheel A, thepinion B being located in front of and on the same plane with the axleof the drive-wheel, all as described.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of October, 1879.
